What it does

Kortix Image is an agent skill from kortix-ai/suna. Recipe: produce a Kortix image (hero, OG card, social card, thumbnail, cover, blog image, illustration, UI asset). Load kortix-brand first. This skill covers sizes, tools, generation, compositing and export. Use when the user asks to create, art-direct or revise an image for Kortix, agents, sandboxes, coding workflows, launch assets, thumbnails or covers.

Its SKILL.md is about 870 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `evals/evals.json`).

It sits in Media & Creative, covering Social media graphics. The repository describes itself as: The open-source AI Operating System.

When your agent uses it

  • The user asks to create
  • Revise an image for Kortix
  • Coding workflows

Example prompts

  • “/kortix-image”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Confirm the surface, the aspect ratio and any required text or facts.
  2. Write one short prompt: subject, Kortix product truth, direction from art-direction.md, composition, aspect ratio. Keep it tight…
  3. Generate as PNG. Composite the official logo file and any exact text after. Follow brandmark.md.
  4. For the web, also export an optimized WebP (about 80% quality). Set explicit width and height to avoid layout shift. Add descriptive alt…
  5. Reject, and do not ship, any image that matches the reject list in art-direction.md.
  6. Report the files you read and a "Guesses" list, as SKILL.md of kortix-brand says.

What it can do on your machine

Read from SKILL.md and the folder at commit 4d2a7e9. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Kortix Image loads about 872 tokens when it runs. Until then it costs about 93 tokens; SKILL.md has 408 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~93
When it runs · the whole SKILL.md, loaded when a task matches
~872

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 408 words (~872 tokens).

“Turn a visual request into one clean, brand-safe image.”
